Hello,

I am currently working with Qt Designer on a project, still I use a lot of silx widgets also.

Thus I tried to create a plugin to have one of silx widget in Qt Designer. I made up this branch (in my fork) because I may create other plugins for widgets that I need.

I think it could be nice to append this to the silx repository.

However I don't know how really it works, I just created it by using the already existing plugins. So if anything seems wrong or not understand, I would like to have some help, or advices.

Thanks in advance

Alexandre

Hi,

Few comments:

• You can remove PyQt4, we do not support it anymore
• In case, you also can use "promote widget" from Qt designer, which does not require any plugins.

Thanks for your answer,

I think it could be nice to have these as plugins so anyone that uses Qt Designer could use it too.

If you want I can clean the already existing plugins from PyQt4 and refresh the dates.

I will try to "promote widget" as you adviced me, but I am still up to create new plugins for enhance silx if you want to.

Thanks for the contribution.

A few comments:

    def icon(self):
        return icons.getQIcon('stack-view')

This is likely to fail as it is looking for an icon file in silx/resources/gui/icons/ and there is no stack-view.svg or stack-view.png file there. You can use 'plot-window-image' instead.

There is a little bit of doc on Qt designer plugins here: https://www.riverbankcomputing.com/static/Docs/PyQt5/designer.html#writing-qt-designer-plugins

Also, feel free to use the name of your institution as the copyright of things you add.

Hi, I'm closing this PR because development on it is stalled and it has conflicts since PR #3991. Do not hesitate to rebase the branch and re-open the PR if needed.
